Data Science

“
Data science
is
the study of the
generalizable extraction of
knowledge from data ”
Source: Dhar, V. (2013). Data science and prediction. Communications of the ACM, 56(12), 64-73.
16
Data Science
• A common epistemic requirement in assessing
whether new knowledge is actionable for
decision making is its predictive power, not
just its ability to explain the past.
Source: Dhar, V. (2013). Data science and prediction. Communications of the ACM, 56(12), 64-73.
17
Data Scientist
• A data scientist requires an
integrated skill set
spanning
mathematics, machine learning, artificial
intelligence, statistics, databases, and
optimization,
along with a deep understanding of the craft
of problem formulation to engineer effective
solutions.
Source: Dhar, V. (2013). Data science and prediction. Communications of the ACM, 56(12), 64-73.

Three Types of Business Analytics
Optimization
Randomized Testing
“What’s the best that can happen?” Prescriptive
Analytics
“What if we try this?”
Predictive Modeling /
Forecasting
“What will happen next?”
Statistical Modeling
“Why is this happening?”
Alerts
“What actions are needed?”
Query / Drill Down
“What exactly is the problem?”
Ad hoc Reports /
Scorecards
“How many, how often, where?”
Standard Report
“What happened?”

Analytics
Descriptive
Analytics

Big-Data Analysis
• Too Big,
too Unstructured,
too many different source
to be manageable through traditional
databases
32
The Rise of “Big Data”
• “Too Big” means databases or data flows in
petabytes (1,000 terabytes)
– Google processes about 24 petabytes of data per
day
• “Too unstructured” means that the data isn’t
easily put into the traditional rows and
columns of conventional databases

Examples of Big Data
• Online information
– Clickstream data from Web and social media content
• Tweets
• Blogs
• Wall postings
• Video data
– Retail and crime/intelligence environments
– Rendering of video entertainment
• Voice data
– call centers and intelligence intervention
• Life sciences
– Genomic and proteomic data from biological research and
medicine
